Perhaps you should try some spelling variations:
"cover estimation algorithms" » "cover estimation algorithm", "cover optimization algorithms", "cover optimisation algorithm", "cover estimations algorithms", "pose estimation algorithms", "sphere estimation algorithms"
"d_ optimized algorithm" » "d_ optimized algorithms", "d_ optimizer algorithms", "_ optimized algorithm", "_ optimize algorithm", "_ optimise algorithm"
"one optimized algorithm" » "one optimized algorithms", "one optimizer algorithms", "_ optimized algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("d_ optimized algorithm") or ("one optimized algorithm"))) or ("cover estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("d_ optimized algorithm") OR ("one optimized algorithm"))) OR ("cover estimation algorithms")).
• Removing quotes may allow a broader search: (((( d_ optimized algorithm ) or ( one optimized algorithm ))) or ( cover estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("d_ optimized algorithm") or ("one optimized algorithm"))) or ("cover estimation algorithms"))*.
